SPRING-GRIP ATTACHMENT FOR DUMB-BELLS.

Specification of Letters Patent.

Patented July 26, 1910.

Application filed October 18, 1909. Serial No. 523,339.

T 0 all whom it may concern:

Be it known that I, IVILLIAM JAMES Dossnrrnn, a subject of His Majestythe King of England, formerly residing at Shepherds Bush, London, butnow of Clerkenwell, London, aforesaid, England, have invented certainnew and useful Improvements in Spring-Grip Attachments for Dumb-Bells,of which the following is a specification.

This invention relates to detachable grips for use with ordinarydumb-bells and has for its object to provide a more simple andconvenient device of this kind that will be more readily detachabletherefrom, it being merely held in combination therewith by the grip ofthe user without in any way being clipped thereon, a still furtherimprovement consisting in the arrangementof the springsand parts so thatan absolutely straight pull of considerable amount can be obtained,while the gripping member is kept within gripping distance of thedumb-bell handle.

The grip consists of two members one being capable of resting on thegrip of the dumb-bell, the other member being slidably mounted inrelation thereto and normally kept apart by a spring or springs. Thesprings may be of any type secured at one extremity, or other suitablepart, to the hand-gripping member and arranged at the other extremity,or another appropriate part, to engage the shank, stem or handle of thedumb-bell member.

In the accompanying. drawings with reference to which I will nowdescribe my invention:Figure 1 is a side elevation of one form of thedetachable grip in position on a dumb-bell; Fig. 2 is a similar View ofa slightly modified form illustrating a convenient way of employingtension springs.

In the form shown in Fig. 1 of the drawings the grip consists of a pairof springs a b spaced apart and each fastened at the opposite ends totwo members 0 (Z, one (Z of which is shaped to the contour of the dumbbell shank stem or handle e, while the other member 0 is fashioned toform a hand-gripping part. Both members may as shown consequently bealike, and be semi-circular in cross section. The springs a Z) are asshown arranged around spindles f that are fastened at their lower endsto the dumb-bell member (Z the upper member being free to slide on thesaid rods its outward movement being limited by heads formed thereon.The spindles f in this figure are not essential as the springs 5 couldbe used without them. Instead of employing single springs at each end ofthe grip I may employ a plurality which may be so arranged that one ormore can be removed to vary the grip or resisting power of the deviceaccording to requirements.

For use, the member (Z is applied over the dumb-bell shank stem orhandle 6 which is then gripped by the fingers and the other member 0 isgripped by the thumb, whereupon the dumb-bell can be manipulated asrequired. lVhen finished with, the attachment and dumbbell fall apart orbecome detached. The springs a b may also as in Fig. 2 be arranged toact in tension when the dumb-bell is gripped, in which event thespringswould be external to the gripping member 0 which is held by thefingers. The outer ends of the springs a b are in this case attached toloops 7" formed as continuations of the central stems or spindles fwhich are here shown formed from a single piece of wire, and the innerends to the gripping member 0.

Obviously the device could be made in Various sizes and strengths andeven where single springs are employed they might easily be maderenewable or interchangeable with weaker or stronger ones as desired.

What I claim and desire to secure by Letters Patent of the United Statesis 1. A detachable spring grip for use with ordinary dumb-bellscomprising a pair of spaced members, one formed for resting on or incontact with the dumb-bell and the other formed as a hand grippingmember, a pair of straight spindles on which the said members areslidably mounted in relation to each other and springs cooperating withthe said members to keep them normally apart, the whole of the partsbeing so combined that a straight pull of considerable length can beobtained' 2. A detachable spring grip for use with ordinary dumb-bellscomprising a pair of spaced members, one formed for resting on or incontact with the dumb-bell and the other'formed as a hand grippingmember, a pair of straight spindles on which the said members areslidably mounted in relation to each other and compression springsmounted around the said spindles between the two spaced members andcooperating with the said members to keep them normally apart, the Wholeof the parts being so combined that a straight pull of considerablelength can be obtained.

3. A detachable spring grip for use with ordinary dumb-bells comprisinga pair of spaced members, one formed for resting on or in contact withthe dumb-bell and the other formed as a hand gripping member, a pair ofstraight spindles on which the said members are slidably mounted inrelation to each other and springs mounted around the said spindles andcooperating with the said members to keep them normally apart, 15 thewhole of the parts/being so combined that a straight pull ofconsiderable length can be obtained.

In testimony, that I claim the foregoing as my invention, I have signedmy name in 20 presence of two subscribing witnesses.
